I just started around the 1st of the year. I was 290 now I'm down 13 pounds as of today. 277! Pretty excited. I made up my own healthy protein shake and replace two meals a day. It keeps me full for 5-6 hours and I have a lot of energy, no jitters or shakes just positive energy. I'm not perfect. I mess up a lot. I cheat at least 2-3 times a week but I keep trying. And I don't workout. But I am way more encouraged to workout, if I can lose 13 pounds with no exercise imagine how well i can do with exercise.
